The magical things the compiler can do are:

1. Use registers to pass parameters rather than the stack, and have the
variable ALREADY in the register.

2. Inline the called function.

You really can't tell, and in a real application, you will find that the
time taken to put parameters on the stack is NOT your bottleneck. BFN.
